{ x + y = 1 * ( - 2 )
2 x + 3y = -4

- 2 x - 2 y = - 2
2 x + 3 y = - 4
_______________
y = - 6

Subsititute y = - 6
<span>
2 x + 3 y = - 4

2 x + 3 * (-6) = -4

2 x - 18 = - 4

2 x = - 4 + 18

2 x = 14

x = 14 / 2

x = 7

The solution to the system of equations are:

x = 7 and y = - 6

In triangle pqr PQ is equals to PR and angle Q is equals to 80 degree find angle p

Dmitry [639]

Answer: ∠P= 20°

<h3>Step-by-step explanation: Well we know that the sum of a triangle always equals to 180°, so ∠P + 80 +80 = 180° </h3>

∠P + 160 = 180

Subtract 160 from both sides, 160 on the left is cancelled so that 180-160 equals 20

∠P=20°
